Foil Cutter
Heat Sealing Foils, Particles in Wells. A wide variety of heat sealing material is offered by many vendors. The Aluminum foil has a sealing layer applied, which melts at a given temperature (range approx. 140 -180°C). The seal material is often Polypropylene (PP), Polyethylene (PE) or Polystyrene (PS). Customers have observed particles of the size of the needle diameter in the wells. These particles can clog the needle during the aspiration step or if transported and ejected the injection valve port. The new microplate foil cutter pre-cuts the foil before the needle penetrates. The shape of the cutter tip prevents that particles are cut out completely. Rather than falling into the well, the foil piece is still attached to the foil.
The microplate foil cutter should be used with any PAL LC version, where Heat Sealing Foils are used. It is limited to max. needle gauge 22 (standard gauge for LC syringes) and can NOT be used with any kind of regular glass vial septas or for GC applications. The tool is attached to the PAL needle guide like the CombiPAL Magnetic Transport Ring. No changes in firmware settings are needed.
